this is… like every other NativeUI library… a tool for developers to help build NativeUI menus in their script…
so… yes it is ready to use if you know how to use a library in c# and no because this is not a ready to use resource… (or at least it is if you want to test it with the example menu script provided)
you should ask this to the MenuAPI developer…
but for be clear… all the things you see in my menu? MenuAPI only have the color panel and is not possible to add it to a list item… to create the color panel… you must create a secondary list item just for it…
MenuAPI was created as a replacement for NativeUI specifically for C# script development. I don’t see the need to resurrect a discontinued project. MenuAPI is not only different, It’s better. Therefore the features it’s missing that you want should been suggested to be added to MenuAPI, in my opinion.
